User-Defined Edit Specifiers

Users can define their own edit specifiers and implement their behavior in the input edit exit (TIRIEX). These specifiers are treated as literals within the edit pattern specification, and are generated directly into the screen source code unchanged. These patterns are then passed to the runtime to interpret the meaning and edit the field contents on the screen.

User-defined edit specifiers may be individual characters (for example, 9 for mandatory digit) or short strings of characters (for example, DN for day name). Care should be taken that no user-defined specifiers are the same as any CA Gen specifiers. To assist in this effort, CA Gen does not define a specifier that starts with the letter U, thus allowing user-defined specifiers to start with this letter.
